悬停时的Bootstrap可点击菜单

我已经使用jquery自定义了引导程序导航,而不是单击以启用下拉菜单,您可以简单地悬停.但是,我试图得到它所以第一个菜单是可点击的,因为目前它不是.例如,目前BLOG不可点击,但我希望它是.其他类别是可点击的.

有人在bootstrap上有这方面的经验吗？它建立在wordpress上.我用来允许菜单在悬停时显示的jquery是:

jQuery(document).ready(function() {

    var mq = window.matchMedia('(min-width: 768px)');
  if (mq.matches) {
    jQuery('ul.navbar-nav li').addClass('hovernav');
  } else {
    jQuery('ul.navbar-nav li').removeClass('hovernav');
  };
    /*
    The addClass/removeClass also needs to be triggered
  on page resize <=> 768px
    */
  if (matchMedia) {
    var mq = window.matchMedia('(min-width: 768px)');
    mq.addListener(WidthChange);
    WidthChange(mq);
  }
    function WidthChange(mq) {
    if (mq.matches) {
      jQuery('ul.navbar-nav li').addClass('hovernav');
    } else {
      jQuery('ul.navbar-nav li').removeClass('hovernav');
    }
  };


});

css是:

@media (min-width: 768px) {
    .navbar-nav .caret {
        display:none;
    }

    .navbar-nav .open ul {
        display:none;
    }

    .navbar-default .navbar-nav > .open > a,.navbar-default .navbar-nav > .open > a:hover,.navbar-default .navbar-nav > .open > a:focus,.navbar-default .navbar-nav > .active > a,.navbar-default .navbar-nav > .active > a:hover,.navbar-default .navbar-nav > .active > a:focus {
        color:#555;
        background:none;
    }

    .navbar-inverse .navbar-nav > .open > a,.navbar-inverse .navbar-nav > .open > a:hover,.navbar-inverse .navbar-nav > .open > a:focus,.navbar-inverse .navbar-nav > .active > a,.navbar-inverse .navbar-nav > .active > a:hover,.navbar-inverse .navbar-nav > .active > a:focus {

        background:none;
    }

    .navbar-default .navbar-nav > .hovernav > a {
        color:#555;
    }

    .navbar-inverse .navbar-nav > .hovernav > a {
        color:#969696;
    }

    .navbar-default .navbar-nav > .hovernav:hover > a,.navbar-default .navbar-nav > .hovernav:hover > a:hover,.navbar-default .navbar-nav > .hovernav:hover > a:focus {
        color:#333;
        background:transparent;
    }

    .navbar-inverse .navbar-nav > .hovernav:hover > a,.navbar-inverse .navbar-nav > .hovernav:hover > a:hover,.navbar-inverse .navbar-nav > .hovernav:hover > a:focus {
        color:#F7F7F7;
        background:transparent;
    }

    .navbar-default .navbar-nav > li:hover {
        background:#e7e7e7;
    }

    .navbar-inverse .navbar-nav > li:hover {
        background:#080808;
    }

    .navbar-nav .hovernav:hover > .dropdown-menu {
        display:block;
    }
}

使用matchMedia/media查询来完成您正在执行的操作时遇到的问题:

许多触摸设备的媒体查询与桌面相同.

悬停不存在触摸.IOS采取悬停,一次点击触发下拉2点击到链接,BUUUT android不能这样工作.因此,在触摸设备上,这些下拉菜单将无法访问.如何正确地做到这一点:

检测Android,IOS和Windows 8手机上的触摸和非触摸.

删除.dropdown链接上的属性数据切换 - 删除此选项允许单击在该切换上工作.

如果没有触摸,则将删除属性包装在if语句中

将悬停脚本包装在no-touch if语句中

有触摸设备的后备,以便他们可以到达第一个菜单项

我在Android上测试了这个.在授予/接受之前,在IOS,Windows 8和其他设备上进行测试.应该顺利工作.
